Both classical RL [1]}, [2]}, [3]} and HRL have been used in ITS [4]}, [5]} and RS. To our knowledge, this is the first time they are combined.
While the field of RL-based ITS is still young and presents several limits [6]}, it could address the complex problem of supporting students dealing with the diverse and enormous environment of social media.
Still, the additional flexibility of RL-based RS comes at the cost of a higher complexity, particularly in terms of training and evaluation setup [7]}, as well as deploying in real world applications [8]}, [9]}.
